Question on how to add a double jump and eventually a wall dodge

Sorry I know this is super late, but I am working in version 4.26 and I don’t understand why I would want to override any of the functions when setting the JumpMaxCount to 2 already gives you doublejump. The only case I could see it as a necessity is when you want the player to have two jumps no matter what. even if they haven’t jumped but are in the air. I am new to all this so I am just looking for confirmation or guidance.
